Hi guys im new here.
I wanna make dual wan load balance (first w/o fail over) i tryed with few tutorials but this not working i think because i wanna use it in different way.
I have 12km bridge on rockets M5 i wanna make another bridge and load balance my all trafic on this two bridges.
I wanna distribute all trafic for 2 bridges and later maybe fail over if any1 will down.
i tryed this http://aacable.wordpress.com/?s=dual+wan but its dont work
